" We are apt to think that Satan is most powerful in crowded thoroughfares. It is a mistake. I believe the temptations of life are always most dangerous in the wilderness. I have been struck with that fact in Bible history. It is not in their most public moments that the great men of the past have fallen; it has been in their quiet hours. Moses never stumbled when he stood before Pharaoh, or while he was flying from Pharaoh; it was when he got into the desert that his patience began to fail. David never stumbled while he was fighting his way through imposing armies; it was when the fight was over, when he was resting quietly under his own vine and fig tree that he put forth his hand to steal. The sorest temptations are not those spoken but those echoed. It is easier to lay aside your besetting sin amid a cloud of witnesses than in the solitude of your own room. The sin that besets you is never so besetting as when you are alone. –George Matheson. "
